Do you have too many applications already installed on your system? Or maybe your system has an antivirus that is making your laptop slow. I would suggest you to get rid of unnecessary programs that you seldom use. Also, make use of cloud based antivirus programs like Immunet and Panda Cloud. Your RAM looks fine. Hopefully, this should solve the problem.

The bottleneck could be your video card.

Try removing temporary files… That works for me
